Optoelectronics devices based on closed-shell organic small molecules and polymers have proven themselves as disruptive technology in display applications. Their ability to interchange light absorption or emission with electrical generation or excitation has allowed for the development of organic light emitting diodes (OLED), organic photovoltaics (OPV) and other devices with commercially relevant performance and costs. However, the fundamental electronic structure of these closed-shell materials imposes limitations on their use. The excitonic nature of these materials means that for every bright, optically accessible (singlet) state there is a corresponding dark (triplet) state at a lower energy. The presence of dark triplet states is the cause for both the lower efficiency and lower stability in current generation organic optoelectronic devices relative to their inorganic counterparts. We propose to generate an entirely new set of optoelectronic materials based on open-shell (radical) organic materials where the lowest energetically excited state is an optically bright state, thus eliminating the major loss mechanism in current organic optoelectronic devices. In addition, the proposed materials can have high-spin which can be optically (or otherwise) manipulated opening up the possibility of using organic materials in next generation quantum technologies.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
